Course Overview

2022 dates: July 15-17 & July 22-24 (40 hours over two long weekends)
Fridays 2:00pm - 6:15pm EDT; Saturdays/Sundays 8:00am - 5:30pm EDT

Columbia University’s Department of Environmental Health Sciences offers a 40-hour course to meet the Nuclear Regulatory Commission (NRC) Class C Radiation Safety Officer (RSO) training requirements.  The curricula is designed for individuals working in academia, industry, and government laboratories seeking training in the safe handling of radioisotopes to meet local, state, or federal regulatory and/or training requirements. Participants that complete this course will fulfill the 40-hour requirement as stated in 10CFR33.15 - Requirements for the issuance of a Type C specific license of broad scope:

At least 40 hours of training and experience in the safe handling of radioactive materials, and in the characteristics of ionizing radiation, units of radiation dose and quantities, radiation detection instrumentation, and biological hazards of exposure to radiation appropriate to the type and forms of byproduct material to be used.

The NRC requires any organization that uses radioactive material to have a licensed, designated Radiation Safety Officer (RSO).  This course is designed to help such organizations apply for or renew their license for use of radioactive materials. The course is not intended to meet the licensing requirements for medical use of radionuclides or fluoroscopic imaging.

Course instructors, with faculty appointments at Columbia University and the Columbia University Medical Center, are experts in their fields.  They include faculty from the Center for Radiological Research, the Department of Environmental Health Sciences, the Department of Medicine and the Department of Environmental Health & Safety.
